摘要： Mechanochemical fabrication produces electroceramics using oxides as starting materials. The fabrication starts with mixing industrial ceramic oxide powders. Electroceramic phases are formed by reacting the oxide powders in a mechanochemical chamber, which is a wear-resistant cylindrical vial with one or more solid balls inside. The formation of electroceramic phases of pervoskite structure and fine crystallinity are activated by mechanical energy or a combination of mechanical energy and thermal energy. Sintered electroceramic materials and components are fabricated when compacts or green bodies made of the resulting ceramic powders are densified at the sintering temperature. The technique can fabricate a wide range of PbO-based ceramics such as Pb(Mg⅓Nb⅔)O3 (PMN), Pb(Mg⅓Nb⅔) O3-PbTiO3 (PMN-PT), Pb(Mg⅓Nb⅔) O3-Pb(Zn⅓Nb⅔)O3-PbTiO3 (PMN-PZN-PT), and other PMN-based relaxor ferroelectrics, Pb(Zr1−xTix)O3 (PZT) and PZT-based piezoelectrics at sintering temperatures as low as 900° C.
